Xcode : module name "" is not a valid identifier while running XC unit test

Question

Trying to run XCTest with my CocoaPods set up using SDWebImage, and I can only see this error as below. Any suggestions?

:0: error: module name "" is not a valid identifier Command /Applications/Xcode8.3.1.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc failed with exit code 1

But as soon as I edit the scheme and uncheck the test inside the builds, I am able to run the app on simulator but can't run the tests.

Did a clean build it wont work if the product module name is missing for test targets — Max, Jul 24 '17 at 21:20

Always make sure all your test targets has the PRODUCT_MODULE_NAME set to $(PRODUCT_NAME)

Can I add **PRODUCT_MODULE_NAME** to test target? I get There are already **PRODUCT_MODULE_NAME** so I am not able to add this to test target. – Tommy Jan 31 '18 at 06:12

And ensure that PRODUCT_NAME does not include characters like a dash. – Morten Holmgaard May 25 '20 at 06:39

I was able to fix the problem by following the steps below while migrating from Xcode 11 to 11.2:

Select the target
Go to Build Settings.
Then scroll down to Packaging
Product module name
If you have spaces in your module name, replace them with underscores

It should be noted that hyphens are invalid characters which should also be replaced with underscores. – Tyler Wood May 19 '22 at 22:51

In this case your need to $(PRODUCT_NAME:c99extidentifier) for PRODUCT_MODULE_NAME.

c99extidentifier allows using dashes in the PRODUCT_NAME.

Also this is the default project value which can be inherited in each target.

Locate the macos folder in your Flutter project.
Open the Runner.xcodeproj project file within the macos folder using Xcode.
In Xcode, select the "Runner" project in the project navigator on the left-hand side.
Go to the "Build Settings" tab for the "Runner" target.
Look for the setting named "Product Module Name" under the "Packaging" section. This setting determines the module name for your macOS app.
Verify that the module name is a valid identifier. It should consist of alphanumeric characters and underscores, and it must start with a letter.
If the module name is empty or invalid, provide a valid identifier. You can use the default value "Runner" or choose a different name that suits your project.
Once you've updated the module name, clean your project by selecting "Product" from the Xcode menu, then choose "Clean Build Folder".
Try building and running your macOS app again to see if the error has been resolved.
